To aZZlwi-om, it may concern! A lle it known that I, PAUL HANSMANN, acitizen 'of tlieUnited States, residing at.

Long Prairie, inthe county of Todd and lState of -Minnesota, havevinvented certain new and useful Improvements inAdjustfable Tongues, ofwhich the following is a'V 'specification- 'My' invention. relates'toiii-proveniente in adjustable tongues for separators' and 'the' like',vits object being to provide an improved construction of tongue which maybe iirmly ,andv claimed..

In the accompanying drawings forming part of this specication F igure' 1is-,a plan view'of iiiy ,invention and connected' nia- `chine axle, Fig.Q-is a lside elevation of the Same, 'F ig. 3 is'a planview of myinvention partly broken away and siiowing thetoi gue in adjustedposition, Fig. 4 a-perspect'ive view-.0f a portion of the in v ation,Fig. 5v

In the drawingsri represents the trout axle of the machine to which myinvention is applied. B represents the tongue having pivotal connection2 `with thccross bar 3 fl'a'iiiit l0 through whichailji'istalily'extends t iiitzibly connected vas by means 'of links' 4'withthe axle. .'ll innerl end of the tongue vIl eonsists of a'pair ot'Vinterspaced vplates 5 connected at their 'forwaiil ends to the top andbottom oil the solidportion of thel pivoted tongue'.l The cross 'bar 3is -torined with a. centratforwar'dly Vextending rigid tongue (S whichstandsv in alinement'with the ,pivoted tonguewhen-fthey saineis `innormal position. Curvedrbars-f connect. the front end' of the rigidtonguewit'h'tlie'ends of 'the cross bar., said curved bars'forining atrac-k for the pivoted tonguewhen the. sanie isadjiisted.

ln order to`turn sii'cd angle aud'hold it in such position I providetheftollovi'ng mechanism. IIaving pivotal siippprtS in the iiiterspaccdplates 1) for'iiiiiig the end of theirigiil tongiir is the tongue 4 toany del-I a screw rod'll. The screw rod 1l has john' nal support at itsends in a bracket l2l which bracket has central pivotal support 123between the plates adjacent tov the front end of therigid tongue. Iprovide one end of the screw rod with a suitable handle lll.

In operation the turning of the handle'ld will rotate the screw rodcausing the screw to travel through the nut and turn the tongue upon itspivot to the desired angle with the axle. It will he evident thatrotating the shaft in one direction willcause the tongue-B to travel toone side of the Vfixed tongue while the opposite rotating of the shaftwill turn the tongue to the epposite side of the fixed tongue. Thechanging -angles of the fixed and pivotedto'ngues is compensated for inthe adjusting mecha-` nism by the pivotal support of the bracket l2 tidof the nut wit-hin vthe bracket.

I claim as my invention: f

v1. In combination with a vehicle, a tongue having'pivotal connectiontherewith, a relatively short rigid tongue and extending ifo-rwardlyinline with said pivoted tongue when the saineis in normal position, anut pivotally 'supported upon the end of saidrigid tongue and a screwrod carried by sald pivot l tongue and threaded through said nut,

2. In combination with a vehicle, a for- 'Wardly extending tongue havingpivotal connection at its inner end therewith, a rigid member'.extending forwardly from said vehicle, an adjusting connection betweensaid rigid member and. said tongue forward of its pivotal support, saidadjusting connection` having pivotal support upon said tongue and apositive driving connection with the center of the forward end of said.rigid member, said adjusting mechanism being actuable to, carry saidtongue to either side of the pivotal, support of Asaid connection." v

3. In combination with a vehicle and .its

cross bar, a tongue having pivotal connecvtion therewith, a relativelyshort forwardly" extending tongue rigidly connected with said. crossbar, a nut-carried Aby the' free end --of said rigid tongue, a bracketsupported by said pivoted tongue, ascrew rod carried by said bracketand'threaded through said nut -ind :in actuating handle for said rod.

4I'In combination Awith a tongue having 11o ,pivotal support at itsinner end, a siuli pole extending firwardly from the supporting ivot ofsaid first mentioned pole, an adjusting connection between the end ofsaid stub pole and the adj acentj. part of said pivoted pole including ascrew shaft having a central pivotal support upon said pivoted pole anda screw threaded traveling oonnection with the end of said stub poleallowing said pivoted pole to be adjusted an# gularly past the free endof said stub pole.

5. Inlcombination with a vehicle, aforwardly extending tongue havingpivotal support thereon at its inner end, lmeans for angularly adjustingthe tongue from a point forward of its pivotal support comprising ascrew shaft having central pivotal support upon said tongue at a pointforward of its pivot, said shaft having screw threadedvconneotion witha' ixed support alongside its pivotl support upon said tongue.

n combination with a vehicle,'a forwardly extending tongue havingpivotal connection therewith at its inner end, a rigid member extending4forwardly from said vehicle, and an adjusting mechanism connecting'saidtongue forward of its pivotal supvport with said rigid member at anunvariable location on said rigid member, and means for operating saidadjusting mechanism to carry said tongue to either side of said rigidmember.

7; In combination with a vehicle, a forwardly extending tongue havingpivotal, connection at its inner end therewith, a rigid member extendingforwardly from said vehicle in aiinement with the pivotal support n ofsaid tongue, and an adjusting mechanism entirely and wholly .supportedby said tongue at a point forward of its pivot and by said Vrigid memberat an unvarying point, said adjusting means constituting a positiveadjusting mechanismbetween said member and tongue to allow said tongueto be angularly turned upon'its pivot from side to side of said rigidmember.

8. In combination with a vehicle, forwardly extending tongue having piotal connection at its inner .end therewith, a. rigid `member extendingforwardly from said vehicle, and a. screw threaded connection betweensaid tongueforward of its pivotal support and with said rigid tongue atan unvarying point, said screwthreaded connection allowing said tongueyto swing angularly on its pivot tol either side of said rigid member.

In testimony whereof I aiiX my signature in presence of two witnesses. i
